JamStream Clipper

Cut the moment while it is still happening.

Send any live stream to a receiver address. It is recorded as it arrives, so you can click a point on the timeline, review it, adjust the start, and have a clip in the right shape for social in seconds.

Any RTMP encoder

OBS, vMix, a hardware box, or a Studio show. Paste one address and keep streaming as usual.

Always recording

A 48-hour rolling window of everything that arrives. Nothing to schedule.

Clips in seconds

Click, review, nudge, cut. 16:9, 1:1 or 9:16, then download or post to YouTube.

How it works

From encoder to clip in four steps.

Clipper sits beside whatever you already use to stream. It does not replace your encoder or your platform; it records what passes through and lets you cut from it.

  1. 1

    Point your encoder at us

    We give you a receiver address. Paste it into OBS, vMix, a hardware encoder, or whatever you already stream with. Your existing stream keeps going wherever it goes.

  2. 2

    Everything is recorded

    From the moment the signal arrives, the stream is captured continuously and kept for 48 hours on a rolling window. Nothing to press, nothing to schedule.

    48h rolling · no gaps

  3. 3

    Click, review, nudge, cut

    Click anywhere on the timeline to jump there. Watch the moment back, move the start a second at a time until it lands, pick a length, and cut.

Formats

Three shapes, one moment.

Cut the same moment in whichever aspect ratio the destination wants. Pick it before you cut; the clip is rendered to size, not letterboxed.

Details

The parts people ask about.

Encoders
Anything that outputs RTMP: OBS, vMix, Wirecast, Streamlabs, hardware encoders, or a JamStream Studio show.
Retention
The last 48 hours of the incoming stream are always available. Clips you cut are kept until you delete them.
Precision
Nudge the start in one-second steps and preview before you cut, so the clip begins where the moment does.
Output
MP4 files in 16:9, 1:1 or 9:16, downloadable immediately. Post to YouTube from the timeline; other platforms are coming.
Who cuts
Anyone with a browser and a sign-in. A second person can clip while the producer runs the stream.

Who it's for

Any stream long enough to have a best bit.

Sports and matches
The goal, the save, the finish, on social before the crowd has left the stands.
Conferences and keynotes
Quotable minutes from a long day, cut by someone in the back row.
News and community broadcasts
The moment that matters from a two-hour council meeting or service.
Long-form creators
Highlights from a stream that is still running, in the format each platform wants.
